Resumo
BACKGROUND
Idiopathic Generalized Tonic-Clonic Seizures (GTCS) are frequently encountered in adults. Their successful control is necessary to improve the quality of life of these patients. Valproic acid is a simple branched-chain carboxylic acid and lamotrigine is a phenyltriazine derivative. Opinions differ in regards to their effectiveness in idiopathic GTCS.
OBJECTIVE
To compare the effectiveness of valproic acid and lamotrigine in newly diagnosed adults with idiopathic generalized tonic-clonic seizures.
METHODS
The present prospective randomized study was conducted on 60 patients suffering from idiopathic GTCS. Thirty patients received valproic acid and rest 30 patients received lamotrigine. All patients were followed regularly monthly for one year for treatment response and adverse effects.
RESULTS
After 12 months follow-up, 76.67% patients taking valproic acid and 56.67% patients taking lamotrigine were seizure-free. Common adverse effects recorded were nausea, dyspepsia, headache and skin rash.
CONCLUSIONS
Valproic acid is more effective than lamotrigine as first-line drug in the treatment of adults with newly diagnosed idiopathic generalized tonic-clonic seizures.
